Mobile phone blocker is a mobile phone blocking program or mobile phone detection system, designed to prevent unauthorized mobile phones while allowing authorized mobile phones to run. Blocking cell phone signals can prevent certain critical foundations, unauthorized calls to courts, military installations, or certain environments that need to manage cell phone activity to control the control.

Please note that in some states, cell phone jammers are illegal. Although attention to information rejection has long been an integral part of the PLA’s doctrine, this jammer is mainly used in military locations or other places where the use of mobile phones is prohibited.

Drones and jammers are the biggest threat to airports

The Ministry of Civil Aviation has proposed a draft regulation that allows the use of drones for any purpose, but with certain restrictions.

While the Ministry of Civil Aviation has legalized the use of drones, government agencies are testing jammers that can disable drones that can pose a threat to safety.

A device designed to block drone communication systems is currently being tested at Delhi airport. Helicopters consisting of the Central Industrial Security Force (CISF) and the National Security Guard will also be dispatched as back-up personnel for emergency situations.

“Although the proposed guidelines for civil aviation state that the five kilometers around the airport is an uninhabited area, regulatory violations cannot be ruled out. Drones are typically managed by operators through a system of remote communication. The equipment we are testing will block the communication system., After that, the operator will no longer be able to control the drone.

Jammers Portable Handheld

The Home Office (MHA) plans to enact legislation to prevent the misuse of drones, especially near airports. Although airport security forces have been advised that drones are considered a potential security threat, no guidance has been issued on how to react when such aircraft are sighted nearby.

“Right now, drones are the biggest threat to airport security, with the exception of wave jammers. They are frequently observed and – currently there is no provision for shooting down flying objects. The CISF provides security, but has yet to decide who will deal with air threats. The Aviation Ministry will oversee the drone actions, but MHA must call for safety. ”

The source said MHA will issue a notice applicable to airports across the country.

The Ministry of Civil Aviation has proposed a draft regulation that allows the use of drones for any purpose, but with certain restrictions. Asked about safety, Aviation Minister RN Choubey said technology is being developed to neutralize rogue drones.

The ministry designated airports and international borders as unpopulated areas and stipulated that their use for commercial purposes requires special permits from aviation regulators. However, government agencies will not be bound by these guidelines.

The center invited the public to make suggestions within 30 days, then will make the necessary changes by December 31 to legalize the use of drones, and use drone jammer to prevent them if necessary.

About the need to use interfering devices in public places

Many people don’t think installing cell phone jammer in schools is a solution, but because children have access to the internet in several other places, such as at home or in open Wi-Fi areas in the city. It’s a very good plan. Adolescents do not have enough maturity to use the Internet properly. From time to time, out of curiosity or under pressure from peers, they may come into contact with content they shouldn’t have. Even if someone accidentally makes such a mistake, it is a very good idea to install jamming devices.

Apart from basketball, what makes me more happy than sports is being able to watch movies in the theater. This is a rare hour and a half for me to get away from the real world and immerse myself in the fantasy of others. Using a mobile phone in the theater is distracting. Like a drunken fan of sports games, it’s distracting. If you look carefully, a nearby ringing phone suddenly interrupts your thoughts, which is terrible.

If you’re attending an emergency meeting and don’t want to join unwanted calls or messages during an important meeting, you can take advantage of mobile phone signal interference technology. Using 3G / 4G Phone Jammer, this technology allows people to avoid calls and text messages without turning off the phone. When this technology is enabled, the signal from the base station will be blocked directly and you will not be able to communicate with others via your mobile phone.

I heard that some devices can prevent eavesdropping and this is true

There are equipment to prevent eavesdropping

More precisely, this is a technique called “scrambling”, namely jammers and jammers. With the popularity of mobile phones, this interference has become popular among the public.

Interference is a device that interferes with radio waves used in communication devices such as mobile phones. When this kind of interference occurs, it interferes with radio waves emitted by mobile phones at a certain distance from the device.

Places that are susceptible to interference include concert halls, movie theaters and hospitals where the use of mobile phones is restricted.

Recently, signal jammer has been installed around bank ATM machines, which are often used to prevent transfer fraud. Many people may be familiar with this news.

Moreover, this interference is an effective preventive measure to prevent the use of radio waves for eavesdropping.

Interference can also prevent eavesdropping

You can use scrambling to block listening. Several scramblers are commercially available and can be purchased by the public.

Jammers can be divided into two types.

Types of blocking/blocking radio waves

Types of hard to hear

There are two types of phone scramblers: one that blocks radio waves and causes interference, and one that makes speech difficult to understand. You can use any of them to stop eavesdropping.

You can use a single encryption machine the same size as the apartment room to protect your privacy, so as not to be eavesdropped. Therefore, it can be expected to be an inexpensive method to prevent eavesdropping.

However, this method of preventing interference requires some precautions to be kept in mind.

Notes on using interference

Cannot completely prevent interception

There are two types of scramblers, but neither can completely interfere with listening.

The performance of 3G/4G mobile phone jammers that the general public can buy is very limited, and the type of blocking/blocking radio waves can interfere with radio waves up to 2.4Ghz, but cannot block radio waves beyond this range.

Also, the type of sound that is hard to hear does not mean that you can mute it by completely muting your voice, as the name implies.

You may need a license to use the scrambled device

Some models send mobile phone interference signals. This powerful interference radio can only be used with the permission of a third-level professional terrestrial radio technician.

If used by an undocumented person with interference model qualifications, a violation of the Radio Law will result in severe penalties.

Even if you block the interception of spies, it will interfere with the communication of the phone, so it is difficult to hear or hear the communication with the phone. There is a danger of touching people.

You will not be caught in commercial facilities or public transportation

Blocking commercial facilities or public transportation violates the Radio Law.

Even if it is unethical to use a mobile phone on a bus or train, do not bring the jammer into the car, but only use it as a jam avoidance device.

In order to prevent eavesdropping, there are plans to install interference in the home or office, but there are restrictions where interference can be installed and where interference can be used.

Jammer-mart’s mobile phone signal jammer is recognized by consumers

Many friends who use mobile phones have this kind of distress, that is, the signal of the mobile phone often has problems.

Mobile phone signal interference in urban village rental houses helps to rest

The shadow behind the splendor of every big city is the village in the city. For example, there are many large and small urban villages in Guangzhou. Shipai Village is the largest and oldest among them. People’s first impression of urban villages is crowded, noisy, and a lot of garbage. The alleys are densely packed, with wires and spider webs crisscrossing overhead.

Because the village is too dense and surrounded by high-rise buildings, the village in the city has a weak signal or even no signal at all in addition to being dark and humid. However, most of the people living in urban villages are fresh graduates or young people who have come to the city to struggle. The lack of mobile phone signal is very difficult for young people to accept. The lack of mobile phone signal not only affects their social activities, but also affects their job prospects. Therefore, many renters hold a mobile phone when they look at the house, and when they come in, if there is no signal in the house, they immediately shook their heads and left.

So, how to solve the problem of bad mobile phone signal? The cell phone jammer is a wireless communication device, which is different from general electrical installations. It may seem simple to install such wireless communication devices, but there are many knowledges in it:

1. First of all, before installing the equipment, fully test the signal and electromagnetic environment to determine the type of equipment, wire and antenna to be selected. To complete this work, it is difficult to do without relevant instruments and professional knowledge. Many people did not understand the reason and bought the equipment and materials at will, but the results were ineffective, and money was wasted.

2. Secondly, during the installation process, there are certain tricks in the design, layout and connection of the circuit. The same equipment and materials, let professional and technical personnel and ordinary electricians to install, the effect will be different, let alone ordinary people.

3. Once the equipment is installed, it needs to be debugged carefully. Equipment debugging is a complex and professional work, which is often far from perfect, and it is difficult for it to be a professional.

4. Finally, the current mobile phone signal amplifiers on the market are mixed, and most of the products are not guaranteed in quality. Many machines only have amplifier circuits, but there are no quality control and anti-interference control circuits. It felt good at first, but it didn’t take long to get worse. Such an amplifier is not only easily affected by environmental changes, but also has a great impact on the surrounding electromagnetic environment, and even interferes with the normal operation of the base station.

At present, many rental houses in urban villages have installed cell phone signal amplifiers, but most of the owners buy them and install them by themselves. In addition, because of the desire to be cheap, the quality of the equipment purchased is very poor, so the signal effect is not good. How many companies have made the outdoor signal environment more and more complicated.

China Mobile and China Unicom have issued a license to use mid-low frequency test frequencies in 5G systems. Among them, China Telecom and China Unicom have obtained licenses for test frequencies in the 3500MHz band, and China Mobile has obtained licenses for test frequencies in the 2600MHz and 4900MHz bands. Therefore, it is safe to use 5g jammer within the range. China Unicom and China Tele have secured a more international mainstream spectrum, but the story of China Mobile is much more complicated. In terms of subdivision, China Mobile has acquired 5G test frequency resources in the bands 2515mhz-2675mhz and 4800mhz-4900mhz. Of these, 2515-2575mhz, 2635-2675mhz, and 48800-4900mhz bands have been newly added, and 2575 bands have been added. -2635mhz prioritized China Mobile’s existing td-lte (4G) frequency.

Do I have the right to ban the use of mobile phones during working hours?

Employers may limit employee rights and personal freedoms. However, that does not mean that it is possible to completely ban the use of mobile phones during working hours.

No, it is very dangerous to generally and absolutely ban the use of personal telephones.

Limitations must be justified by the nature of the task being performed and proportional to the purpose pursued (Labor Law, Art L.1121-1).

The rules of procedure cannot be justified by the nature of the task to be performed and cannot include restrictions proportional to the purpose pursued (Labor Law, Article L.1321-3).

However, for safety reasons, you may prohibit the use of the telephone while driving the device, handling dangerous products, or when there is a risk of interference with electronic devices. However, employees working alone in the office are prohibited from using their mobile phones. The phone doesn’t seem to be justified.

3G Mobile Phone Jammer

Using cell phone signal jammer can be annoying to other employees. Therefore, it should be used with caution. For example, you can set usage rules such as asking an employee to put the phone in vibrator mode or making a call outside the office.

Commission Nationale Informatiqueet Libertés (CNIL) authorizes use for personal purposes within the company, provided that the telephone and the Internet are of reasonable use.

Remember that employees fulfill their employment contracts in good faith. There needs to be a reason to use the phone. Don’t sacrifice work performance. In case of abuse, employees can be punished. You need to be able to prove abuse of your personal phone during working hours …

Pros and cons of mobile phone signal jammer

Nowadays, with the rapid development of science and technology, traditional mobile phones are becoming more and more intelligent, and they have become an important communication tool indispensable in people’s daily work and life. Of course, the negative effects caused by mobile phones are also immeasurable. Negative impacts in special scenarios and specific times have become new leak channels and new criminal methods, posing a threat to the security of confidential information. Therefore, it is urgent to strengthen the management and standardized use of mobile phone signal blockers.

Mobile phone signal jammers are mainly used in places where no mobile phone communication is required, such as in various examinations, office premises of confidential departments, gas stations, etc. Because of their easy installation and simple use, more and more companies use signal blocker. And the equipment signal is always in a relatively static state, which will not interfere with other electrical equipment, and has played a certain role in some special places.

GPS signal jammer

The mobile phone signal jammer is also called mobile communication jammer, mobile phone signal isolator, conference security device, etc.The signal jammer transmits a strong signal consistent with the frequency of the mobile phone’s downlink frequency band, and is tuned with the signal sent by the base station to the mobile phone, so that the base station sends to the mobile phone The downlink signal is deformed and cannot be recognized by the mobile phone, which interrupts the connection between the mobile phone and the base station. Simply put, its main function is to make the phone unable to use normally. Its essence is to implement electromagnetic interference to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network.

However, with the promotion of signal jammers, it has also brought some adverse effects. The wide use of signal jammers will interfere with the normal use of surrounding residents, causing residents to use mobile phones without signals. If the shielding range is shortened, there will be a lot of It is also difficult to control the blind angle and blind zone, the shielding edge distance, and the long-term coverage is wide, the power will be large, and the radiation generated will also affect the human body. Therefore, the quality of a mobile phone signal shielding device depends not only on the The effective shielding degree of mobile phone communication signals, but also whether the radiation pollution produced by it meets the national electromagnetic radiation protection standards

Especially in government agencies, once the staff of the agency accidentally leaked the content of their work, they could easily be stolen by illegal elements. This is a very dangerous thing for agencies and agencies. In order to prevent such incidents from happening, government agencies will be equipped with mobile phone signal jammers or mobile phone signal shielding cabinets to avoid leaks.

Cheap GPS jammers pose a major threat to drones

Jammers that can be bought for as little as $ 50 threaten commercial drones, but options exist.

With the rotors buzzing and the airframes racing through the air, drones can be very dangerous if flights don’t go as planned. Much has been gnawed about the FAA’s measured approach to implementing commercial drone guidelines, but the fact is there are real dangers, even from bad actors using inexpensive GPS jammer.

phone signal jammer

GPS signal jamming technology is evolving, decreasing in size and cost. These days jammers can be bought online for as little as $ 50. Jamming has long been a threat to military assets and is becoming a commercial problem today as commercial drone shipments become a reality and attacks become ubiquitous around the world. This threat now affects trade, law enforcement, and defense drones on critical missions.

During a choreographed light show in Hong Kong in 2018, 46 drones fell from the sky due to a jamming device. The resulting property damage and loss of hardware is estimated to cost an estimated HK $ 1 million. Almost all drones have security protocols that can be used to send them home or to a safe landing site in the event of a disruption. However, these functions were found to be ineffective at the Hong Kong show.

“These are professional-grade drones already built with technology that will guide them back to the launch site,” Anthony Lau Chun-hon, director of the events committee, told the South China Morning Post. “But the signals were so strong that many of them just fell out of thin air.”

Drones and their services are decidedly dependent on GPS signals. Although the drone may have backup methods (INS / OPS), GPS references are still required for positioning, navigation and stabilization. GPS attacks are therefore the easiest way to shut down a drone and potentially cause harm to life and property.

The good news is that solutions for drones are arriving with commercial quality and coming straight from the defense sector. One comes from a company called infiniDome, which makes a device called a GPSdome that is built into a drone’s GNSS receivers and uses a unique interference filter system that combines the patterns of two omnidirectional antennas. GPSdome analyzes the interference signal in real time and feeds its properties into infiniDome’s proprietary algorithm to filter and reject attacking RF interference, so that the UAS continues to rely on GPS signals during a jamming attack. If an interference signal is detected, the GPSdome notifies the operator of possible signal interference.

Easy Aerial, a leading provider of autonomous, drone-based surveillance solutions for commercial, government and defense applications, recently added GPSdome to its range of autonomous unmanned aerial systems for military use.

“We chose GPSdome because it was a proven solution that was a perfect fit for the various missions our customers routinely fly in some of the most inhospitable and hostile environments in the world,” said Ido Gur, Co-Founder and CEO of Easy Aerial. “While our systems have multiple redundancies on board, GPS signals for maintaining position, navigation and timing accuracy are critical to ensure uninterrupted operation.”

This type of lightweight, small form factor, low power shielding technology is a critical step towards widespread adoption of commercial drones. Other companies like Sepentrio also take GPS interference in drone applications with integrated sensor solutions seriously.

It is certain that the problem of GPS interference and spoofing will receive more attention in the coming days. Fortunately, developers seem to be beginning to see tools that they can use to counter the growing threat.
